Figs. 1 to 4 inclusive.

hanger bolt 29 is provided with a T-head 30, which is inserted into theinterior o the bolt-retaining casing V by passing the same through theauxiliary slot 3l located between the adjacent lower edges o'ithe plates26, and then turning the head ot the bolt until it stands'in theposition shown in Figs. 3 and 13. It will be seen that by making thehead o suiicient length, the bolt cannot be turned entirely around, butwill abut against the side walls oi theI plates 26, 26, so that the nutsupon the bolts29 may be turned without rotating the bolt itself.

In Fig. 16a' modified yformof T-head bolt is illustrated, particularlyadapted to prevent the rotation of said bolt during the setting oi thenut thereon. lIt will be seen that the plates 26, 26, which formtogether the bolt-retaining casing 25', extend longitudinally oi thegirder 22 and that the slot 24 oi said girder extends downwardly'fronithe bolt-retaining casing to the under side or face oi 'the girder- 22,so that the slot 24, as a whole, is a T-slot in the particular iormillustrated in The bolts 29 fasten the hangers 32 to the girder 22, asshown in Figs. 3 and 4, said hangers forming a wellknown meanstor-supporting the main shaft 33.

In Figs. 5 and 6 l have illustrated a slightly modified i'orm oibolt-retaining casing and in Fig. 12 I have illustrat-cd an enlargedsection oi this particular form oi bolt-retaining casing, -with one olthe-hanger bolts attached thereto, said bolt-retaining casing 25consisting of two plates 26, 2 6 having their adjacent edges parallel`and separated one irorn the other to form an auxiliary slot 31. Theplates 26, 26 have 'horizontal flanges 27, 27, said flanges beingconnected by a plate 34, which is lastened' thereto, by means oi rivets28. The

bolt-retaining casing 25 is contained in a slot 24 formed in the girder22. To the bottom of this girder are fastened channel irons 35 by meansof the Jl-bolts 29, the heads of said bolts being retained Within thecasing 25, as illustrated in Figs. 5 and 6. Cross-beains extend from oneof the channel irons 35 to the other and are'secured thereto byclamp-bolts 37, and to these crossbeams are fastened the hangers 38 orthe countershafts 39.A

In Figs. 7, 8 and 9 I have illustrated a modiiied form of bolt-retainingcasing consisting oi a tube or pipe 25 embedded in afgirder. 22 andprovided with an auxiliary slot 31 extending longitudinally. thereof.The pipe 25 is embedded in thev girder .22 in a slot 24` which extendslongitudinally oi the girder 22. andex tends from the auxiliary slot 31.downwardly to the lower face o' the girder 22 `The hanger bolts 29 are-provided with heads 30.-having a curvilinear orrn upon the under sidethereof adapted to fit the interior of the pipe 25". The-hanger 32 isattached by the bolts 29 to `the girder 22, as shown in Figs. 7 and 8.

'In Figs. 17, 18 and 19, the bolt retaining easing. 25?

. consists ot two angle plates 263 having an auxiliary' slot '313between. their adjacent edges, said angle plates beig held against theunder face of thev girder 223 by" means oi bolts 40 and cross plates 41,said bolts 40 being anchored permanentlyin the girder 223. The hanger323 :is held against the .plates 26LbyT-headed hanger bolts 293',asillustrated. in--Flig`. .-18. The heads ofsaid bolts project upwardlyinto a slot 243,

. heads resting upon the upper faces oi the plates 26, 264.

In Fig. 20 anothcr form of my. invention is illustrated in which a slot241 is iinied in the lower face oi the girder 22, said slot being partlyinclosed by two flat plates 264, 2G". '.lhe plates 264" are fastened tothe under Y side oi the girder 224 by meansof bolts 40and plates 70V41*. The adjacent edges of the plates 264. 264 are separated one fromthe other, forming an auxiliary slot 31" through which the hanger boltsproject, the heads of said bolts entering the slot 244 and the underside ot said In each of the different forms illustrated a bolt-retainingcasing isprovided, said casing partly surrounding a slot constructed toreceive the heads of the hanger bolts, both casing and slot extendinglongitudinally of the girder. `Thebolt-retaining casing ispreferably-an- 8O chored in the girder in each case by any desirable andpractical means, and in Figsf 7 and 8 have illustrated such anchoringmeans, the same consisting oi a U-shaped rod 42 embedded in the concretecomposing the girder 22, with the bend loi the rod inside thebolt-retaining 85 casing 25.

I do not wish to beunderstood as limiting my invention to any particulariorm of bolt-retaining casing or to any particular means for attachingthe saine to a concrete girder. stood as limiting myseli toanyparticuiar form oi slot extending longitudinally ol said girder andpartly surrounded by said casing, my invention' consisting, broadly, in.so constructing a concrete girder, or girder of any v'tire proofconstruction, that a slot will be pro- 95 vided in said girder adaptedto receive and retain the heads of bolts projecting from said girderthrough said slot and beyond one face of said girder, forming apractical, convenient, and strong means for readily attaching to thegirder hangers or xtures of different 10Q kinds and styles, said meansbeing adjustable to varying positions and requirements. In carrying mydevice into practical operation, the girders are provided with ametallic casing ol any"desirahle form, as in some of the formshereinbeore de- 105 scribed and illustrated, and after the building iscon-v structed the head of the hanger bolt is passed upwardly throughthe auxiliary slot 31 and through vthe slot 24 and into the portion ofthe slot surrounded by the bolt retaining casing 25.A The bolt head isthen 1 1() turned at an angle, of ninety degrees sc that it will extendacross the casing 25 and the hanger is thengi attached to the girder bymeans or the bolts 29 and. i

-the nuts thereon` It willbe readily seen that the bolts 29 may be movedlongitudinally et the girders to 115 any desired location, thusaffording a readymeans o f attaching the hangers to the girders at anydesired point. f A

While I have referred, :Eer convenience, to a girder l in both thespecification and claims, I do not wish-` to be understood as limitingmyself to the particular portion oifa buildingknown technically as agirdcr, Vasit is evident that without departing 'from the spirit-of myinvention the device hereinbeiore described and illustrated in thedrawings may be applied to columns, walls, ioors, and iloorbeams etavlire prooi buildingor the attachment thereto of hangers and lixturesofvarious kinds.- I'have throughout the'vspecication andclaims referred to.a girder as a concrete girder, Athis being a term known tothe trade asre- Neither do I wish to be..under 9U ferring to a girder formed as awhole or in part of cement or like material, which, at one time in theprocess of construction, is 'soft and finally becomes hardened bysetting.
